I bought this isolation transformer for my home studio to safely break the ground loop causing some hum/noise. Decided to go a bit further and really dig into the product since I did not know much about the more advanced features. I am NOT being sponsored by the manufacturer. They however have been very helpful and receptive to my suggestions to change the under/over voltage protection threshold points
I need some help with how to program microcontrollers. Please reach out if you know anything about what is involved, tools, software, adapters, etc. I can handle the soldering. The microcontroller is a NuvoTon N76E003AT20. I'd love to learn how to reprogram myself, but if it's easier for me to send you the new programming file to upload to the microcontroller and you send me the chip to install I'd be willing to pay you for your services.
